Moreover, the resulting all-perovskite tandem solar cells achieved an efficiency of 28.48%, which is certified by a public test center. The encapsulated tandem device retains >90% of its initial efficiency after 750 hours of maximum power point tracking (MPPT) under simulated AM 1.5G illumination.
This yields an open-circuit voltage of 2.21 V and a certified power-conversion efficiency of 29.1% for all-perovskite tandem solar cells, measured under the maximum power-point conditions. Substantial open-circuit voltage loss and inherent non-radiative recombination hinder efficiency improvements in wide-bandgap perovskite solar cells.
Nature Materials (2025) Cite this article Monolithic all-perovskite tandem solar cells present a promising approach for exceeding the efficiency limit of single-junction solar cells. However, the substantial open-circuit voltage loss in the wide-bandgap perovskite subcell hinders further improvements in power-conversion efficiency.
The development of green and efficient photovoltaic technologies is crucial for global environmental protection. The two-terminal (2T) tandem perovskite solar cells (T-PSCs) have attracted tremendous attention with a detailed balance limit of ∼ 43 %, and an empirical limit of 33.6 % .
Tandems minimize the amount of thermalization with multiple absorbers responsible for sections of the solar spectrum rather than a single absorber responsible for the entire spectrum (Figure 1) Single-junction solar cells are fundamentally limited to 33.7% efficiency, while double-junction tandems have a theoretical efficiency potential of 46.1%.
All-perovskite tandem solar cells (TSCs) consist of a wide-bandgap (WBG, 1.75–1.8 eV) top subcell and a low-bandgap (LBG, 1.2–1.3 eV) bottom subcell, exhibit superior power conversion efficiencies (PCEs) compared to single-junction perovskite solar cells (PSCs).
